Automatic hive entrance opening for Natupol hives

Assimilation lights change the growing conditions in the greenhouse: days become longer and in winter months the artificial light (which is poor in UV) dominates the natural light. Bumblebees have difficulties with their orientation when there is little UV light, and this hinders effective pollination. It is possible to release the bumblebees only during favourable light conditions by timely opening and closing the flight hole. This not only improves the pollination performance, but also increases the development and lifespan of the colonies. With WIRELESS BEEHOME it is possible to open and close the flight holes automatically.

Quantity to be used
1 WIRELESS BEEHOME - receiver for each active hive
1 WIRELESS BEEHOME - central transmitter (incl. 2 clamps) for each site or compartment
The central transmitter is available without timer , this version is to be steered via the UNI exit of the climate computer, and with timer for steering based on the timer's settings.

Each WIRELESS BEEHOME receiver can open or close the flight hole of the hive to which it has been connected. One central transmitter directs all receivers within the same site or compartment. It is possible to manage the position of the flight hole in the following ways:

  • via a signal from the climate computer though a connection between a UNI-exit or 'free exit' on the climate computer and the central transmitter, or
  • according to the settings on the timer that is connected with the central transmitter (for the version with timer).

Protect WIRELESS BEEHOME transmitters and receivers against condensation and droplets under gutters, moisture from sprays, and longlasting direct sunlight.

WIRELESS BEEHOME - central transmitter

  • Mount the transmitter with the clamps on to a post on a central position of the site where is has to operate, on 1,20 m height. Choose a shadowy place.
  • Fix the transmitter in such a way to the post that the distance between the post and the antenna is at least 25 cm.
  • Connect the long cord with the (220 V~) power supply.
  • After pressing the switch TESTEN, the transmitter sends a testing signal during one hour. On each WIRELESS BEEHOME receiver that has just been switched on, this causes the shutter to move slightly during 30 seconds as a proof of receipt of the testing signal.
  • Both WIRELESS BEEHOME transmitter and receiver are set on address 1 as default. There are 8 different addresses (frequencies) available. Adjacent sites or compartments with own transmitter must used different addresses to avoid undesirable mutual influencing.
  • The response time of WIRELESS BEEHOME receiver on the transmitter varies from 6-11 minutes, in case of another transmitter operating nearby this can increase to approximately 25 minutes.
  • After a power-cut, check the time on the timer, and adjust if necessary. Normally the internal battery keeps the timer going in case of a power-cut. If this is not the case, replace the battery of the timer.
  • During a power-cut the transmitter does not send any signal, and thus the position of the shutters will not change. When the power comes back, the transmitter directs the shutters to the position which is set for that particular time of the day. This may cause shutters open or close later than normal.

Control of the WIRELESS BEEHOME - central transmitter


  • Open the hives some hours after sunrise, since (especially in the darkest months) only then the natural light provides sufficient UV light for the bumblebees to orientate.
  • Close the hives 2 hours before sunset. This gives the bumblebees enough time to get back to their hive under natural light conditions.

Option 1: control via the UNI-exit of the climate computer (24 V DC)

  • Connect the UNI-exit of the climate computer with the IN-port of the transmitter
  • WIRELESS BEEHOME opens at 24 V and closes at 0 V. Polarity of the UNI signal has no influence.
  • Set the times for opening and closing on the climate computer.

Option 2: control of WIRELESS BEEHOME via timer

  • Put the timer in the socket on the transmitter. Connect the plug on the short cord with the timer.
  • Set the timer as instructed in its directions for use. Choose 'switching daily'.
  • Set the times for opening and closing on the timer.
  • With the HAND press-button on the timer it is possible to operate the WIRELESS BEEHOME manually.


  • Place the colony on its definite place in the greenhouse, and leave it there to calm down for at least 1 hour.
  • Put every hive on a separate place. If nevertheless 2 hives are stacked, separate them with the polystyrene panel that comes with the WIRELESS BEEHOME receiver. Provide enough free space for the shutter to move.
  • Remove the slide-door that closes the flight hole, in the afternoon, after the closing time that is set for the other hives (beware: some bumblebees may escape!).
  • Slide the panel on the WIRELESS BEEHOME with the two round holes into the opening where the slide-door was just removed.
  • Switch the WIRELESS BEEHOME on by moving the little switch on the side in postion I. In case the shutter was not already closed it will close now, also when all other shutters are open. From that moment the receiver listens to the transmitter and wait for the command to OPEN. If this command has been sent already on that day, the hive will only open after the next OPEN command is sent on the following day. From the biological point of view this is better for the colony.
  • It is possible to check the receipt of a receiver. First press the TESTEN button on the transmitter, then it will send a testing signal during 1 hour. Then switch the receiver OFF and ON again. As proof of receipt, the shutter will move slightly during 30 seconds. All other WIRELESS BEEHOME receivers continue operating as normal.
  • Each WIRELESS BEEHOME receiver checks its own battery condition. When a battery is nearly empty, the shutter moves to its furthest OPEN position and stays there until batteries have been replaced. It is recommended to replace the batteries of all WIRELESS-BEEHOME receivers when 2 or 3 of the devices have indicated that their battery is empty.


  • WIRELESS BEEHOME is particularly useful during the darkest months (November-February) in crops under artificial light. If the equipment is not used during the rest of the year, remove them from the greenhouse and store clean and dry. The 2700 mA/h alkaline batteries that are supplied with the apparatus are of excellent quality and cannot leak. These batteries last for approximately 1 year with normal use.
  • After every replacement of batteries, spray them with anti-moisture spray, also the contacts and electronic parts. This gives better conduction of power and protects against aging> Use i.e. Valma anti-moisture (Koppert can supply), by all means no plastic spray!
  • Newer WIRELESS BEEHOME versions have welded battery package. To replace this, just disconnect plug and connect wit new battery package.

The following instruction for the use of the internal menu of both transmitter and receiver is only relevant if WIRELESS BEEHOME operates in two adjacent sites or compartments

Internal menu WIRELESS BEEHOME - transmitter

  • Through the internal menu it is possible to change the address of the transmitter. The default address is set on no. 1.
  • Unscrew the 6 screws on the front side of the transmitter, and carefully release the lid from the box.
  • In the middle of the box there is a small print with a button and a led (Light Emitting Diod).
  • For the operation of the menu the transmitter must be connected to the 220 V AC power. So be careful!
  • All WIRELESS BEEHOME receivers on the same site must have the same address as the transmitter.

Change address on central transmitter

  • Press the button 1x LONG to enter the menu structure
  • Press 1x SHORT to reach menu 2.
